I have this propery in my C# class:

[Required]
[RegularExpression("^[0-9]*$", ErrorMessage = "Document must contain only numbers")]
public string DocRegister{ get; set; }

Beyond that, I need to validade the length of the string. It's acceptable the length 11 OR 14
How can I do that with Data Annotations?

I mean, I couldn't do:

[StringLength(11, MinimumLength = 11)]
[StringLength(14, MinimumLength = 14)]

right?

I don't think this is possible with data annotations. You could use a library like FluentValidation to do this, though. – Jonesopolis Sep 17 '20 at 13:59

As workaround you can try to write regex which will do that) – Guru Stron Sep 17 '20 at 14:03

Or write your own custom [annotation](https://stackoverflow.com/a/3413875/2501279). – Guru Stron Sep 17 '20 at 14:05
